with a followup deduction talking about the issues specific to our project. >> including down stream processing and digest our feeding and a configuration and sizings and then the final site visit was a foods waste faultd fulton facility to produce the bio solids for land application for farm fertilizer and to help with the business fleet in oswald norway so the group was able to touch the end product at each the wastewater treatments and understand the types of bio solid materials the southeast plant will produce and looked at

the power and heat facilities to help to highlight what you do with the maximizing of the digesters and so for lessons learned the team learned the hydraulic process provides a golden opportunity to help to meet the objectives as mentioned include a system that the fits on a constrained site and odors contained within the system and production of a class a solids sf puc can take pride in and we've got commitment and responses manufacturers to provide startup assistance and operator training assistance

so where are we're going the team is the project team is moving towards completing the csr with the hydraulic process as part of the workshops u upgrades. >> i have a question how old or neutrality is this. >> i was really surprised when you look at it and pick it up we were in a shed filled with this material is it smells less than garden effort ligatures when you go into a home depot when you go into one of the stores you definitely know when you're in the garden section when you walk into the shed you can't smell anything that offense it is piled up. >> my wife grew up around a watering plant in chicago and in

the summer depending on the wind it is strong but this technology is almost odor not at all so people that don't little around that. >> i how the it was odor nudity don't get me wrong the process upstream you have thickeners that provides the odor but this end process didn't smell nearly as bad. >> just to add this component is one where you deal with the solids so this is the most odd reducing reduce and since we're building new digesters but another part of the treatment is the head works i bring in it into the plant that is something as part of the sewer system program we're going to look at the odors and the loiblgdz where

we separate the solid from liquid and the odor control coming out of those facilities we're committed to the odors but this is a large component of line item a lot of the odors so that's one of the excitement. >> a couple of things to add it was amazing i want to thank everyone for come on the trip it was a brutal trip we start on monday which was memorial day and actually took tours and looked at it plants people had to travel on sunday people got there sunday so people traveled on saturday it was an 11 or 12 are hour flight and a 9 hour

differences so question traveled the average of 12 or 13 hours a day on a buses or train or plane to go to each site so coming back we end on friday most people traveled only saturday it was a big commitment we tried to jam if as much stuff as possible one the concerns so for food waste with emilio they went the food waste i guessed was 95 degrees very humid and the ventilation inside was noted good the oerldz with so bad unbearable i heard that tom lost his cookies he said he didn't. >> (laughter) so from the wastewater guy does

that is bad we actually wanted to go and really experience that ourselves they fixed the ventilation that made some modifications but one of the challenges when you've taken in the food waste into the plant that area has a lot of odors you're bringing in stuff 2, 3, 4 or 5 days to contain that odor was one of the challenges the whole plant was dealing with so that's ongoing and where you get the food wastes one of the ideas working with ecology but they need to sort of that we can't take food wastes and stuff like that but that's where the most challenge is that ecology has separating food wastes the other thing that was amazing in

ireland they have before profit running tim's water is for profit they're putting can be in what it is doing the example they're using is like without this pretreatment it is like eating an apple you eat it and try to digest the apple but with high temperature and velocity it makes it into apple sows sauce so you know how quickly you digest this therefore you don't use a lot of attention time in the digest so not use as many digesters that's one of the selling points but it was interesting you go to one of the for profit utilities when you go there little staff a lot of the materials they run the failures it is two different models so i

want to point out i think that was a great experience and i was strongly recommend despite what people may write this is the biggest decision we're making and i would encourage whoever is interested to look at it this technology really quip yourselves bus this is something you'll leading leave a legacy for the next generation. >> can i ask about the food waste so the program you saw one that was the next generation; right? audience. >> yeah. the can be process is more they've spent a lot of money refinancing the process it is still the same by interested the food wastes that producing produces more energy so they

generate more power enough gas converted to power up their fleet that's something they're proud about but the city invested a lot of money in this plant that's one of the things we're concerned concerned about because i don't know if you've been to awe i didn't it is very expensive a hamburger and soda is expensive but you can't afford to eat a hamburger. >> just to follow up the food wastes liability right now is looking like it might not be viable. >> maybe tommy can add but one of the challenges to get the food wastes to the plant. >> i also think when you look at the bigger picture of the defying if i had with the hetch hetchy power it seems like partly from the recycling

prospective but the energy generations that's significant to power a fleet but as a potential viable energy source. >> good afternoon, commissioners tommy with the general manager from waifrment yes. the food wastes tour was exist what we saw a food waste plant in one thousand acres of farming i went through this place previously and i didn't toss my cookies by the collected them in plastic bags everything is automated it was hot outside but not meant for people to be inside everything is automated our challenge in san francisco ecology whoever the garbage collectors sort it we want the

raw materials, however ecology has moved forward with the digesters to take the sold wastes out of san francisco to process somewhere else, however, we're interested remember we had the recycle program with brown grease we're interested in the - everyone felt hotels in san francisco have an intercepter with trucks that is what we're interested in we know douglas double the gas production adding that that is basically liquid and get money on the front end might charge you $0.11 a gallon and collect them thousand of gallons a day we're interested and for the tippy too. >> we only have a limited amount of spice space for

accomodation. >> one question on the can be it is i guess the organization we're talking about but i noticed there's another one organization is that the same technology or a xeefrt in the field versus another item. >> it's the same technology the exerts in the field have the same process and different tank size one process that performed a process slightly definitely but thermal hydraulics the same this is the xeefrt but can be has been around but the selection of technology we want to be on the leading edge not the bleeding edge we of the people that have a 20-year track record china signed up for 5 more and to be able to see for

those who don't know we sent people f to look at it this in 1995 we were on top of the candy a lot of the researchers and engineers were interested in f this process this can solve a lot of problems the potential to reduce the amount of volumes for trucks to buy somewhere around 40 percent of landfill whatever we're going duo to do the the product this is a larger footprint can be has the first installation took 3 years and the last installation three weeks that's how you know because now is the production factory they've come it comes on a railcar or truck and ready to go pretty much. >> i think the one thing not

mentioned we looked at the the company they didn't get it to run to capacity their righting a lot of the teams whereas weaves begun to you know can be is it can be up and running so this is why we've felt comfortable this one was pyramid to moved on. >> it was oxford that has both instead of. >> yes. interesting they have 6 different digesters or 6 systems one - all of them but one were can be and the other one 53 lee i can't they may convert that to can be as well but trying to go look at the different technology. >> i was saying that there's experience with both installed

can be helpful. >> they've said they can convert to can be. >> thank you. >> any other comments questions? >> well, thank you the next item is ivy will come up and give the contracting update and the 14 b local business entrepreneurs and two are updates we want to give you an overhead the public works contracting the administrative code chapter 6 we always talk about and give us pretty much an update of the local business enterprise program and the changes that are big deal being proposed when you look at your agenda items and look at contracting you get a familiar

why we do thing chapter 6 for example, is at the framework in which we contract in the city and is it so not only governs the t c but 7 other agencies with that ivy. >> thank you very much so good afternoon, commissioners i'm rectifying i didn't fine with the program administration bureau i'm going to talk about the public works contracting policy and our local business enterprise program those are two sections that govern many if not most of the puc contract both the codes are being changed i want to provide we with a refresher as well as changes the ferries is the public works contracting policies and procedures in the san francisco chapter 67 this addresses contracting rules

and regulations for the construction services and second is local business entrepreneurs program codified under the administrative code which governs our local enterprise program that is the monitoring department formerly the human rights commission. >> all right. so the purpose of chapter 6 is and so forth the city's rules and requirements for selecting contracting for design construction and infrastructure section of public works public works is denied as any construction or repair of any public building or infrastructure it is at least partially paid with city money the logos you see here are the departments that have authority to procure chapter 6 contracts

the duplicate department of public health they do maintenance they're considered a chapter of department but not much. >> can i interject those are only the departments can also do the contracting the police and fire other departments in the city can't perform construction they typically go through the department of public works so those are the main agencies that do the contracting for contracting and the types of contracting all chapter 6 public works are construction currently require some form of a competitive solicitation or bid process the consulting process include the services related to construction projects education

are design and engineering construction management first says that public rings and financial and it services are under a different code in formal contracts are under hundred and $10,000 we have to obtain 3 bids and have appropriate lines of the work and the formal contract are greater than hundred and $10,000 and those are pubically standardized those are what you see when with you have a request for proposal that grandmother you the board of supervisors approval is required for all professional service contracts over $10 million or is term of own 10 years. >> construction contractors include work thank you maintained think of construction but the work nevertheless

requires a contract licenses like landscaping and concern maintenance for boiler and painting the low bid have secured for professional contracts we use for the formal bidding methods the informal is higher than 4 hundred and 40 thousand for the equipment and materials not part of the professional consulting services you all see these maintenance repair and those contracts with indefinite quantity of work are contained within a price book those are extensively bid and construction management general contractor allows for the owner to bring on a construction contractors like

providing in sight not open for deduction this method creates opportunity for collaboration among the stakeholder and most likely you'll see in front of one for the digesters design is traditionally thirty percent complete when we bring on the c mc contractors a build one of the objectives will collaboration and the designer of record and the general contractors are brought on board earlier than the c m g c. >> so current key requirements contractors must pay prevailing wage on outline construction contracts the local hire requirement since 2011 and increased the employment's for all san franciscans covers

construction projects over 4 hundred and 40 thousand this threshold is requested to be increased to $600,000 i'll talk about that and i thought i would go over what happens when we have a procurement for failure of bids once in a while on this one or two bids if no bids are received and changing the contract will likely result in more contractors bidding we'll usually rebid from the analysis is though the department feels that the modification of the contractor are additional outreach will not likely result in more birds we'll come before you and may renegotiate with any qualified bird when you have one sole bird one

responsive bird it is the price of the one bid not exceed the engineers estimate we'll requirement the project to that bird if the one sole birds the price exceeded the engineers estimate we'll do an analysis whether the outreach of the modifications of the contract will result in more than one bid price substantially lower than the one we receive if yes we rebid if no, we come to you to renegotiate with that sole bird one the keys the cost of the work can't be higher than the price of the bid with an informal quote beforehand late we received one responsive bid and no other responsive bids

received from the price didn't exposed the engineers estimate we'll come co-to you with the award of the contract from the bid price preceded it we'll analysis whether or not the bird qualifications were to an reduce and not necessary to actually perform the work or if we feel that we changed something in the contract that the nonresponsive birds will want to bid again if we say yes to one the factors than we rebid if no, we come to you for approval to negotiate with that one bird i know that was a lot but okay outreach in creating opportunity those are at the heather's of

the contracts and for our public works procurement public advisement is getting the word out it relates to the number of bids received so all contracts are pubically advertised in newspapers and the sfgov website and we send out overwhelm nos to contracts and subcontracted about a month or two before we advertise the contracts they can start to become ready we we tell them what trades the type of project and the value we know the will do it and when the advisement is going to be this is the focused outreach we don't do a blatant on e-mails but look at the things like spam we look at the right contractors that are certified in the categories

that are identified in the engineers estimate and do target outreach to those on capacity building we work with project managers to look at the escapees scopes of work and whether or not they can be bidding on smaller contracts that provide opportunities for smaller contractor and still meets the overall project goals we're really approved proud of the center a hub for buildings for the strategy session we have a trainings and connect for computers and used as a plan room 0 you'll contracts from the airport or dpw we have their specifications there free for any contractor to take a look. >> so reasons for change

amazingly the late a change was 15 years ago so in june of 2014 the controller's office condone a working group with the chapter 6 department in earlier saw the logo and the city attorney's office the zoning administrator the office of contract mix and the risk manager and monitoring distribution and other stakeholders we met every others week for about a year they were very lively discussions and considered more than 50 recommendations and we settled on about 34 moving forward. >> no one other just -

>> all righty so summary proposed changes the first one is the threshold increases so currently, the threshold is 4 hundred and 40 thousand we're proposing to increase to 6 hundred thousand this effects the amount of work performed by city employees and enable the departments to set aside larger contracts for smaller contractors and it will increase the task odor that are allowed under job order contracting and then under it - the changes will be modifying the evaluation process and the two ones you all will see most in our contract are for design builds and

construction also known as contract refilling this is when a contractor is - after we have a designer of record and bring on a general contractor. >> can we just i wanted to highlight that i think that is important for us to talk about the different types of contracting we're going to start shifting from the low bid the low bid you have plans and specs a contractor gets the document and bids a hard bid and evaluates the low bid we voluntary manslaughter it you bring in a contractor on earlier that performs the contract activities and they become did contract manager they'll break the design plans into a trade

package and bid those to the substances and so it is great to have the contractor on board earlier they've perform up to 25 percent the work but the great thing they'll solicit the bids for trading packages the reason we find this is a great alternative when you bring the c m g c on you worked have angeles rather than price thirty how to engage local businesses how do you help with the local hire hire so they can be creative one thing to offer the food truck into the facility we want to make sure it's a local food truck so through the process really will
